Jayeye:"What can I do with 400 555s?" A Class D bridge tied load stereo amplifier: 15W per channel into 4 ohm load could use 84 of them Lineup per channel: One 555 as triangle wave generator, one as comparator (low Z audio in to CV pin) to generate a PWM then 20 as inverting buffers, and 20 as non-inverting buffers, with current sharing resistors in series with each output to combine them into a pair of inverted and non-inverted PWM outputs good for >3A. Combine that with 2x RoGeorge's suggested 'Synth' and you are up to 90 555's used, Build four units for the kids of your least favourite colleagues or ex-friends and you'll be universally hated by their parents, and *still* have 40 555's left for your own stock. |
